Then I cracked loose the injector lines and cranked several times at wide open throttle until they were all soaked with fuel, then tightened up the lines.

The car then started right up and ran fine. But, I noticed that the large top bolt on the fuel filter housing was seeping. So, I cranked it down snug and it stopped. But, am I going to have to bleed the fuel system again since there was fuel leaking out of the top bolt? I hate bleeding the system and getting biodiesel all over my engine, which I have to immediately wash off with our hard Phoenix hose water.

If there is air in the system, will it bleed itself out over time, or will it always be there causing problems?
